GENERAL DESCRIPTION
The AD8278 is a general-purpose difference amplifier intended for precision signal conditioning in power critical applications that require both high performance and low power. The AD8278 provides exceptional common-mode rejection ratio (80 dB) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser-trimmed for excellent gain accuracy and high CMRR. They also have extremely low gain drift vs. temperature.

FEATURES
   Wide input range beyond supplies
   Rugged input overvoltage protection
   Low supply current: 200 μA maximum
   Low power dissipation: 0.5 mW at VS = 2.5 V
   Bandwidth: 1 MHz (G = ½)
   CMRR: 80 dB minimum, dc to 20 kHz (G = ½)
   Low offset voltage drift: ±2 μV/°C maximum (B Grade)
   Low gain drift: 1 ppm/°C maximum (B Grade)
   Enhanced slew rate: 1.4 V/μs
   Wide power supply range:
      Single supply: 2 V to 36 V
      Dual supplies: ±2 V to ±18 V
   8-lead SOIC and MSOP packages

APPLICATIONS
   Voltage measurement and monitoring
   Current measurement and monitoring
   Instrumentation amplifier building block
   Portable, battery-powered equipment
   Test and measurement
